| 摘 要： | 面元炮检距分布的均匀性是三维观测系统的一个重要面元属性。本文用面元炮检距均匀性相关系数定量评价面元内的炮检距分布均匀程度,进而分析对造成观测系统采集脚印的影响。通过计算不同参数观测系统的面元炮检距均匀性相关系数,发现炮线距(纵向滚动距)、横向滚动距对采集脚印周期性影响较大,道间距、炮间距对其基本无影响。

| Abstract: | The uniformity of bin offset distribution is an essential bin property of 3D seismic geometry.In this paper, we use the correlation coefficient of bin offset distribution to evaluate the uniformity of bin offset distribution and analyze acquisition footprints.The correlation coefiicient of bin offset distribution with different acquisition parameters is calculated.The results suggest that the source line spacing (inline rolling) and the receive line spacing (crossline rolling) affect more on the acquisition footprint periodicity than the receiver interval and the source interval. |

| Keywords: | 3D seismic geometry offset uniform distribution correlation coefficient acquisition footprints acquisition parameter |
